As there was no validation for the size of a 64-bit atom in an MP4 file, this could have led to a CPU hog when the size was 0, or various other problems due to integer underflow when the calculating atom data size, including segmentation faults or even worker-process memory disclosure. For Debian 8 "Jessie", this issue has been fixed in nginx version 1.6.2-5+deb8u6. We recommend that you upgrade your nginx packages.
